IMPROVED METALLIC! PAINT.

TOALL WHOM IT MAY CONCERNz' Be it known that I, HENRY E. COLTON, of the city, county, and State of New York, have invented anew and improved Metallic Paint; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same.

This invention relates'to -a new combination (if-substances for the formation of a pigment or paint for use on the W and other iron vessels, and-on all iron surfaces, whether such surfaces are exposed to the action of water or air, wherebythe said vessels and iron surfaces are protected from injury from rust, and from foulinby the adhesion of obstructions of either a vegetuble or animal nature; and the invention mainly consistsinformi'fimi'fimmbining oxide of zinc rind the oxide of lead (the latter either as minium or lithnrge) with mineral or animal oils, or the oil obtained from the destructive distillation of coal tar, or from the distillation of bones, and using also a certain proportion of tallow, in which oils the said oxides are to be mixed or ground. I also mix with the above substances, for certain purposes, or to meet certain circumstances and conditions, graphite nrsenious ncid gnd alsoflie silicate of alumina.-

One of the distinctive features of this combination is found in the fact that it contains no vegetable oil. The oil distilled from coal tar, and substances oi a kindred nature, will not support vegetable life; consequently seaweed and marine grasses will not adhere; and the paint thus formed and applied is quite as unfavorable to animal life. The oxide of zinc forrns, when in contact with water, a chloride, which, as is well known, is a virulent poison; consequently barnacles and other living merino obstructions 'will seek locations inore favorable to their'developmont. t I i To thin this point, and render it suitable to be. applied with a brush to the bottoms of iron vessels, and to other iron surfaces, I use a liquid formed of a mixture of coal tar, naphtha or benzole, and common pine tnr or pine resin. y

In forming this paint I use a large proportion of the oxide of zinc. From the fact that this substance contains but little body, it has not hitherto been used for the purpose to which I applj it; but by combining it with the oxide of lead to form a. body, I find, from actual experiment,- that it is admirably adopted to the purpose intended. I I

The bottoms of iron vessels covered with thispaint do not foul -hy-the adhesion of obstructions of either vegetable or animal growth and it is equally well adapted to the protection of iron surfaces from rust, whether such surfaces are exposed to water or air. I

I do not confine myself to an particular proportion as regards the main ingredients used, nor, in fact, to all the particular substances which I may find it necessary to combine with the oxide and animol and'mincrnl oils. It might be necessary to vary the proportions, as well as the iniuor ingredients for vessels making voyages to different parts of the world, as the conditions would vary in diiierent latitudes. Having thus described thy invention, what I claim as new, and desire to secure by Letters Patent, is-

The use of the oxide of zinc and the oxide of-lead, 850., combined with mineral and animal oils,in a point or piginent for covering the bottoms of iron vessels, and other iron surfaces, substantially as dcscrihed.
